QRN'AMENTAL IRON STAIR--BA IL STRUCTURE.

Application'filed May 6,1926. Serial No. 107,0 8).

- My invention relatesto an ornamental iron stair rail structure, moreparticularly to the means of securing the separate members of the siderailing of stairs together, and the objects of my invention are: first,to provlde a'stair-rail structure of this class in which the separatemembers are rigidly secured together withoutwelding, riveting or thelike; second, to provide a stair rail structure of this class in whichthe vertical bar members are provided with recess portions made by a andwhich will not readily deteriorate or get out of order.

With these and other objects in view as my invention con will appearhereinafter, sists of certain novel features of construction,combination and arrangementof parts and portions as will be hereinafterdescribed in detail and particularly set forthin the appended claims,reference being had to the accompanying drawings and to thecharacters'of reference thereon which form a part of this application inwhich:

Figure 1 is a side elevational 'view of the vertical and angular barsshowing by solid lines the position. of the angular bar at approximatelya right angle tothe perpendicular bar before being secured rigidlytogether, and showing by 'dotted lines the angular position of the barwhen the members are rigidly secured in position and ready for use.Figure 2 is a perspective view of the vertical and angular bars vwiththe angular bars shown slightly below the position in which they aresecurely positioned, and Fig' ure 3 is a fragmentary side elevationalview of a stair rail constructed of a plurality of the perpendicular andangular bars in their assembled position.

Similar characters of reference refer to similar parts and portionsthroughout the several views of the drawings.

Thevertical bars -1, and angular bars 2,

constitute the principal'parts and portions I of my ornamental ironstructure. The vertical bars 1. are preferably made of square materialabout one-half inch square.

desired. Theyare each provided in opposite sides with notches 1 and 1which are preferably made by a punch press. It will be noted that on theone side there is a thin oo However, they may be polygon shaped 1f,-

web 1, in each of the notchesand on one I side only. The angular bars 2are preferably about one-quarter 4'?) by one (1'1) or one andone-quarter (1%") lnches and they are provided with square holes 2 whichholes are made to conform to a cross-section of the bar 1 In this caseit is shownsquare and is slightly larger than the bar so that the bars 2will readily slide over the bar- 1; and the upper innercorner of thewalls surrounding the hole 2' is adapted to fit into the notch 1 and thelower .inner corner is adapted to fit into the notch 1 in the bar 1 whenthe member 2. is positioned in the proper angular position to thememberl for forming the proper angle for the stairrail, as shown best inFigure 3 of the drawings it beingnoted that the notches 1" and 1" arepositioned relatively to each other so as to provide approximately theproper angle of the stair rail when finished, it being noted that theweb 1 is crushed when themem bers land 2 are forced to the angularposition with each other as shown by solid andv dotted lines in Figure 1of the drawing,the-

web providing for a-rigid, tight fit of the members 1 and 2relatively toeach other where there is slight variation between the various steps ofthe stairs.

g It will be noted that the upper member 2 as shown'in Figure 3 of thedrawingfits on the upper end of theuprights 1. Therefore the upper notch1 is not complete, the upper portion being cut off Then over the uppermember 2 is, provided a cover member 3 for covering the upper end. Thelower end of the upright ordinarily restsupon the end of the steps ofthe stairs as shown best'in. Figure 3 of the drawing. When assemblingthis structure a plurality of the uprights 1 are placed in the holes 2ofa plurality of the angular bars 2 positioned adjacent the notches 1 and1 in spaced relation. Then the structure is forced to the angularposition by raising the ends of the bars 2 rela tively to the bars 1 andthe bars 2interlocking with the barsl asshown in Figure 3 of thedrawing, and by dotted lines in Figure 1 of the drawings, after whichthey are secured at their ends, providing a rigid interlockingornamental iron structure without welding, riveting or the like. i

In order to furthersupport the structure annular members 4 may beinterposed between theseparate members 1 and 2 and resting against saidmembers as shown in Figure 3 of the drawings.

Though I have shown and described aparticular construction, combinationand arrangement of parts and portions, I do not wish to be liini-ted'tothis particular construction, combination and arrangement but desire toinclude in the scope of my invention the construction, combination andarrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is: '1 In a structure of the class described, aplurality of polygon cross section bars pro;- vided with pairs ofangular notches in "opposite sides of said bars and a plurality of 7other bar s connecting each of the former and V tively to each other.

plurality of square, perpendicular members, provided with a plurality ofpairs of spaced notches in opposite sides thereof-and webs in:

means interposed between said perpendicular and angular bars for holdingsaid bars in separate spaced relation and rigidly securing themtogether. r

In testimony whereof, I-have hereunto set my handat Los Angeles,California, this 7 f 29th day of April, 1926.
